In the past I've owned a Atari 2600 (played a lot), Sega Genesis (played some), XBox (played little), and XBox 360 (played little). PC gaming has always been my main platform starting in about 1985. I used to primarily play strategy games (Civ, Age of Empires, etc), but lately I've had trouble overcoming inertia and starting games of something involving. I still do, but it's not the vast majority like it used to be. I'm playing more games like Dark Souls, Rayman, etc).

The consoles used to be primarily used for driving and sports games. FPS were still played on the PC because I found M+KB control so much easier than a controller. I don't have buddies that I game with, so multiplayer really isn't a concern for me, although I do like leaderboards to compete against with many of you here. I do occasionally play a game (like a LEGO game or Rayman) with my 2nd grade son, but his screen time is limited so it doesn't happen that often.

I'm trying to decide if it's worth getting a console and since I really want to play The Last of Us it would be a Playstation (and I already have a 360 which I may sell). The main points I can think of, which mainly support just sticking with the PC are:

1- Most games I want probably come out on both the PC and the Playstation, so do I really need a Playstation? That money could just eventually finance a new video card.
2- Now that XBox 360 controller support is common on the PC I can just use them for games on the PC that play better with a controller, including my cheap wireless wheel. Since a big draw for the consoles were driving games that I can now pretty easily play on the PC that makes a console less attractive.
3- I don't mind playing in front of a computer screen, so playing from the couch isn't a huge draw. My wife doesn't really enjoy computer games but I wouldn't mind if I could find a game we could play together. A console would probably make this more likely since it is easier to gather around the TV.
4- Are there a lot of great PS games that aren't available on the PC - like The Last of Us, to make a purchase worthwhile?
5- I've gotten used to PC game sales so console game prices may be hard to swallow.
6- Visuals seem to always be better on a PC as long as you have a decent video card - my current card is a Radeon HD7870.

It looks like I could pick up a used PS3 for $140-$170, a new one for $250-$270. A new PS4 for $399. What would be your recommendation - used PS3, new PS3, new PS4, or nothing? If you recommend a PS3, which model. Are some more reliable than others?

Thanks!
